AUTOMATIC WEATHER STRIP FOR CLOS'URES.

Application filed April 17, 1922. Serial No. 553,416.

To @ZZ 'whom t may concern.'

Be it known that I, CARL JOHN HAGsTRoM, a citizen of the United States, residing at Glen Cove, in the county of `Nassau and State of New York, have invented certain new and usefulImprovements in Automatic Weather Strips for Closures, of which the following is a specification. f

This invention relates to builders hardware land has particular reference to weather strips for movable closures, such as casement doors, windows, or other like a building.

Among the yobjects of the invention is to provide a weather strip of a relatively rigid nature carried by and movable with respect to a closure as stated, the weather strip being adapted in the closed position of the door, window, or other -like closure to hug snugly against the sill, frame, or saddle. f

Another object of the invention is to provide a weather strip having a hinged or movable connection with a closure with means for controlling the movement thereof aroundy its axis coincident with theswinging of the closure on its hinges. i

Withthe foregoing and other objects in view the invention consists in the arrangement and combination of .partshereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein,

still for the purpose of illustrating a practi-` cal embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which:

Figure 1 is an inside elevation of a door equipped with the invention. I

Fig. 2 is an enlarged fragmentary vertical section taken approximately on the line 2 2 of Fig. 1 with thedoor in closedposition.

Fig. 3 is an enlarged fragmentary vertical section through the door,V illustrating the same in closed position. f

Fig. 1 is a similar view illustrating the door in a partially open position.

Fig. 5 is a vertical transverse section on the line 5f-5 of Fig. 3.

Fig. 6 is a vertical section on the line 6-6 of Fig. 4.

Referring now `more specifically to the drawings I show a closure 10 mounted to swing around vertical hinges 11 ina frame 12 and over a sill or sa dle 13. By the parts Ofshut. lAs indicated, however, thestri term closure as used herein I wish to be understood as covering broadly` any analogous building element such as a French casement, swinging window,door, or'the like.

The weather strip Mis preferably made of sheet metal. or its equivalent, bent toform a hook shaped flange 15 along its upper edge, while the main portion of` thestrip may have any configuration, depending upon the edge of the saddle with ywhich it is adapted to co-operate when the closure is 1s shown as being bent along a longitudinal line yparallel to the hook 15 forming an ob-. tuse rangle for co-operation withan undercut channel or groove 13 formed in the outer` edge ofthe sill. i i Any suitable means may be provided to so connect thefstrip 111 to the closure as to l provlde for swinging movement thereof around a horizontal axis substantially withinor parallel to the hook 15.

against or close to the saddle when the`clo` The means I prefer to employ vfor khous` ing theweather strip in the lchannel 16 is a sheet metal casing 17 having `along its inner edge a `hookshaped flange 18 providing a trough-like bearing and embracing and supporting the turned upedge or ange 15 ofthe strip and within which casing` the strip is freeto rotate. In the open position of the closure the strip will lie entirely withinthe casing where it may be held either by contact at one endiwith 'the saddle or by special simple kmechanical means. 7

kAsillustrated the means for ejecting the weather strip includes a lever 19 pivoted on a horizontal pivot or bolt 2O within the hous-k ing 21. The head 22 of the levery co-operates `with a longitudinallyv` shiftable plunger 23 I The strip is! adapted to lie 1n nested or housed position which extends through the housing 21 and the adjacent ,lower part or' the closure. A strong spring 24 tends normally to swing the lever 19 to project the free extremity of the plunger from the .closure and by reason of a shoulder or lug 19 on the lower end of the lever positively lift an arm .25 with which it engages. This arm 25 is pivoted loosely upon the pivot v2O :of the lever 19, and through a link 26 secured to the weather strip 214, 'thereby swings the weatherstrip on its horizontal axis to nest within the channel 16 and casing 17;y The lin'k'26 extends 'through a slot 27 in the bottom of the lhousing 17. As the closure is being shut the 'free end of 'the plunger 23 will engage the side `off the frame and effect a longitudinal inward movement thereof as shown in Fig. 3, putting the spring`24 under tension, while an auxiliary lighter spring 2,4', through the medium ofthe arm 42 5 and link 26, tends to force the strip 14 downward into snug but resilient engagement with the saddle, assistedrk by gravity. The auxiliary spring Awill permit 'the Strip to be lifted'even though 'the lever beheld as in Fig. 3. When the closure is open the plunger 23 is released, and under action `of the main spring 24 the same will be shifted longitudinally outward, thereby permitting the main spring to lift and house ythe strip as in Fig. 6, to an out of the way position, and against the force of the spring 24.

As vabove pointed out 'I ymay employ 4mechanical means in co-operation with the weather strip to force the same downward whenxthe closure is shut. As shown in Fig. 2, I pro-vide a combined locking bolt and actuator, the boltI being indicated at 28 for co-operation with the saddle 13 vto lock the closure shut and the actuator being indicated at29 -in the form o'f a finger connected rigidly with a side of the bolt 28. The actuator being movable downward through the upper portion of the casing 17, the end of the finger or actuator pushes downward against the upper and outer surface ofthe weather strip and moves it positively into closed position when the end of the boltA enters the socket 30 'formed in the saddle. Any suitable means may be provided to control the action of the bolt 28. As shown the upper end of the bolt is toothed at 31 for vco-operation with a pinion 32 carried by the shaft of a manipulation knob The rotation ofthe knob to vunlock or release the bolt from'the saddle will ynaturally release the finger 29 frointhe weather strip land so the weather strip will be free `to swing upward with the opening of the closureasalreadydescrihed;

The saddle is shown made of metal, grooved or corrugated on top to prevent slipping thereon, and having a groove 13a on its outer edge below the groove 13, where# by. rain or the .like will be effectively. de-

flected from iowing or creeping over the saddle.V e, j

I claim:

1. The combination with a closure and a casing secured in the vedge of the closure, said casing having a trough-like bearing at its inner edge, of a weather strip having a turned up edge forming a iange having movablev mounting in the bearing, whereby the strip may be housed wholly in the casing or projected therefrom.

2. The combination with a support having an inclosure therein, ot a movable weather strip mounted in saidr inclosure, a pivoted spring pressed arm connected to the weather strip to project the same from said inclosure, a pivoted member engaging the arm, a spring engaging said last mentioned member to overcome the iii-st mentioned spring and hold the weather strip in its inclosure, and a device moved by movement or' the support into closed position to move the said member and permit the spring pressed arm to -force the weather strip from its inclosure.

3. 'The combination with a support having an inclosure therein, of a movable weather strip mounted in ,said inclosure, a pivoted spring pressed aufm-connected to the weather strip to project the same from said inclosure, a pivoted member engaging the arm, a spring engaging saidk last mentioned vmember to overcome the first mentioned spring and hold the weather strip in its inclosure, anda longitudinally movable plunger forced in one direction by the closing operation of the support to move the member to permit the spring pressed arm'to force the weather strip from the inclosure. I Y

4f. The combination with a closure and a pivoted weather strip therein and adapted to swing outward around its axis from one edge thereof, ot. a locking bolt carried by the closure and movable in a direction perpendicular to said axis. and a rigid finger lined upon the locking bolt and projectingk laterally therefrom l and thence parallel thereto for engaging the weather strip to .torce it around itsL axis into snug operative position when the locking bolt is projected into .locking position.

5. The combination with a closure, of a weather strip at the base of the closure and movable around a'horizontal axis, a vertically movable locking bolt carried by the closure and having a linger projecting ktherefrom to engage the weather strip to force the latter into snug operative position when the bolt` is movedv .into locking position, manually operated means for moving the bolt, and mechanical means for moving the weather strip in the opposite direction when permitted by jthe unlocking movement of the bolt and its linger.

f In testimony whereof I affix my signature.
